Shed That Excess Carbon!

In October,
a groundbreaking report from Britain warned that it's almost too late to avoid
climate catastrophe, but that countries can help if they're willing to spend
just 1 percent of world GDP to do so. While most individuals can't build more
public transport or wind-power plants, they can invest in greater energy
efficiency and spend less time on the road.

Although the United States leads
the world in greenhouse gas (GHG) emissions, Australia's per capita emissions
(at over 26 metric tons) are even higher than Americans' 24 tons. Canada
produces 23.7 tons per person, Russia 14 tons, and the United Kingdom 11 tons,
while most Africans generate less than a ton annually. For those of us producing
the most GHGs, the first steps to lowering our emissions can be easy and cheap:

Take public transport to work. The average U.S. car emits
7.3 tons of carbon dioxide (CO2) annually, or about half an American's
yearly GHG output. Offset unavoidable driving emissions by supporting
alternative energy projects (terrapass.com).

Turn down your gas heater. CO2savings: approximately 286 kg a year for
each degree dropped between 21° and 16° C (315 pounds for each degree between
70° and 60° F).

Replace or adjust your refrigerator. Fridges
from 2000 and earlier can produce 427-756 kg of CO2annually. In 2001, average CO2production from U.S. fridges dropped to 344 kg
per unit, and in 2006, it fell to 301 kg. Save up to 189 kg a year by checking
door seals, switching to power-save mode, using a cooler location, defrosting,
and raising the thermostat from 2.7° to 4.4° C (37° to 40° F).

Set your water heater at 49° C (120° F). CO2savings: up to 113 kg a year.

Wash clothes in cool water. CO2savings: 73 kg a year.

These savings are averages and may
be even greater in locations that draw most of their energy from coal power.
The average U.S. conversion factor is .61 kg/kilowatthour, according to the
Energy Information Administration, though coal-reliant North Dakota's factor is
1.02 kg/kwh.

Other switches to consider:

Lighting: Swapping a 75-watt bulb for a 20-watt compact fluor­escent
will save about 334 kg of CO2over
the bulb's lifetime (energyfederation.com).

Appliances: When replacing older units, particularly fridges and
air conditioners, choose Energy Star-certified and equivalent models, which can
use 10 percent less energy than standard models (energystar.gov).

Getting Around: Bikes and electric scooters can be
good alternatives to driving, with many options available (trekbikes.com,
specialized.com, dahon.com, egovehicles.com, evtamerica.com, e-maxscooter.com).
And while we can't drive our way to zero emissions, some cars, particularly
hybrids and electrics, produce less than others. To compare the emissions of
different models and for other energy-saving tips, see fueleconomy.gov.

Green Energy: In some markets consumers can sign
up with a utility that relies on hydropower, windpower, or other sources that
don't contribute to global warming. If not, you may be able to purchase
Renewable Energy Certificates (RECs) to offset your electricity consumption.
For U.S. green power utilities and REC retailers, see
eere.energy.gov/greenpower. For guarantees that the energy you buy is truly
green, look for Green-e certified utilities (green-e.org). In Australia, you
can sign up though the Green Power national accreditation website at
greenpower.gov.au. In Canada, green energy providers can be found at
environmentaldefence.ca/aveda/action.htm.

Travel: Take trains where possible-a single roundtrip flight
can produce as much CO2as a year's worth of
driving. Flying roundtrip from London to New York, for example, can produce 3.8
tons of CO2per passenger. When jet travel is
unavoidable, balance the GHGs produced by supporting alternative energy
projects (atmosfair.de, betterworldclub.com/links/offsets.htm,
nativeenergy.com).

Rebates: Many energy utilities offer rebates for buying green.
